Docker on Windows 7 and Proxy Issues

To install docker on windows 7, you have to download Docker Toolbox from Docker Store

 Note: Docker for Windows is available for free and requires Microsoft Windows 10 Professional or Enterprise 64-bit. For previous versions of windows get Docker Toolbox.

 This installation will also install Oracle VM VirtualBox.

 Once the installation completed, Open Docker Quickstart Terminal, it will automatically create 'default' vm. 

 Execute the following command to confirm the successful installation.

 docker pull hello-world

 if this command download 'hello-world' image successfully, then enjoy. 

 Usually you may face proxy issues if you are behind a proxy. So to resolve the proxy issues, you can set HTTP_PROXY environment variable. But before setting this variable, you have to install CNTLM.

 for CNTLM you can view this post and follow first two steps.

 Once CNTLM started, run the following command in Docker Quickstart Terminal to resolve the proxy issues.

 docker-machine rm default

 click 'y' to delete the 'default' VM.

 docker-machine create -d virtualbox --engine-env HTTP_PROXY=10.0.2.2:3128 --engine-env HTTPS_PROXY=10.0.2.2:3128 default

 'default' is VM name.

 This command will create a 'default' vm and after successfully creation, you can successfully download images from docker hub.

 docker pull hello-world

 if you still face proxy issues, close the Docker Quickstart Terminal and open it again and pull the image.
Enjoy :)

Data Bound Controls in ASP.Net - Part 4 (FormView and DetailsView controls)

FormView The FormView control is used to display a single record from a data source. It is similar to the DetailsView control, except it displays user-defined templates instead of row fields. Creating your own templates gives you greater flexibility in controlling how the data is displayed. The FormView control supports the following features: ·          Binding to data source controls, such as SqlDataSource and ObjectDataSource. ·          Built-in inserting, updating and deleting capabilities. ·          Built-in paging capabilities. ·          Programmatic access to the FormView object model to dynamically set properties, handle events, and so on. ·          Customizable appearance through user-defined templates, themes, and styles. Templates For the FormView control to display content, you need to create templates for the different parts of the control. Most templates are optional; however, you must create a template for the mode in which the control is configur

ASP.net: HttpHandlers

Image
HTTPHandlers: ASP.NET handles all the HTTP requests coming from the user and generates the appropriate response for it. ASP.NET framework knows how to process different kind of requests based on extension. For example, it can handle request for .aspx , .ascx and .txt files, etc. When it receives any request, it checks the extension to see if it can handle that request and performs some predefined steps to serve that request. ASP.NET provides a low-level request/response API that enables developers to use .NET Framework classes to service incoming HTTP requests.So as a developer, One might want to handle some new kind of requests such as requests for .jpg or .gif. ASP.NET provides HTTPHandler to handle requests for .jpg or .gif. An ASP.NET HTTP handler is the process or endpoint that runs in response to a request made to an ASP.NET Web application. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the requ

The Clickjacking attack and X-Frame-Options

Clickjacking  Clickjacking is a type of “web framing” or “UI redressing” attack. What that simply means in practice is that: 1. A user (victim) is shown an innocuous, but enticing web page (think watch online video) 2. Another web page (that generally does something important – think add friends on social network) is layered on top of the first page and set to be transparent 3. When the user thinks they are clicking on the web page they see (video), they are actually clicking on the higher layered (framed) page that is transparent There are two main ways to prevent clickjacking: 1.     Sending the proper X-Frame-Options HTTP response headers that instruct the browser to not allow framing from other domains 2.     Employing defensive code in the UI to ensure that the current frame is the most top level window Using X-Frame-Options X-Frame-Options  originally invented by Microsoft for IE8, but supported by a number of browsers, this idea might have more
